Compare or contrast Macbeth and Lady Macbeth's attitudes using their lines in the conversation they have after Macbeth murders Duncan.

MACBETH.
I'll go no more:
I am afraid to think what I have done;
Look on't again I dare not.
LADY MACBETH.
Infirm of purpose!
Give me the daggers: the sleeping and the dead
Are but as pictures: 'tis the eye of childhood
That fears a painted devil. If he do bleed,
I'll gild the faces of the grooms withal,
For it must seem their guilt.

ANSWER: The important thing to notice about his conversation is that Macbeth goes back to acting weak, like he did earlier in the play when Lady Macbeth had to give him the confidence to kill Duncan. Lady Macbeth is the strong character again. She basically says, "Fine, I'll do it myself." She calls Macbeth a weakling, "Infirm of purpose!" for being afraid of the "sleeping and the dead."
